To' all whom it may concern. -1 5 F I Be itknown that I, Hnnennr B.MOKAHIN, a citlzen of the United States, residing at Molina, in thecountyof Roclrlsland and 5 State of Illinois, have invented; certain newand useful Improvements in li larkerDe vicesfor Planters, of which thefollowing is I a specification, reference being'had therein totheaccompanying drawing. 1

frame comprising the side bars 5, the front bar 61 and the rear crossbar7. The. front" frame comprises the tongue 8, and a cross frame elementindicated,'as an entirety, by 9, for supporting the'seeders 10, 10, therunners, the seeder shaft 11, and the check heads12. The rear frame ispivoted'to the front frame in'the usual way; the sidejbars 5, 5 of the"framebeingf connected thereto The two marker appliances are indicatedilarly constructed "and attached, each comprising an elongated armadapted to-extend ne'cting the inner endto' the planter frame,

andYdeVic-es for -automatically guiding and causing the elevation of thearm as it moves to and 'from its operative position; Each he drawings]indicate that "the usual, chain mechanism'and clutch device can .be

employed for taking power from the' axle 4 H to intermittentlyactuatethe seeder shaftll};

annis composed ofalight rod element15 and'a sleev'efortubul'ar element16, the form; er being longitudinally slidable in the sleeve,

for 'variation of total length," and adapted to be fastened afteradjustment by clamping devices at 33.

Atthe inner end, the sleeve"element"l6 is joined by the verticalhingeelement 17 to the planter-frame; The part 18 is formed or providedwith the said hinge pint'le' 17 and also with an expanded part18f Thelatter is positioned between two lugs or ears 20, 20 formed with orcarried by a station-f" ary bar orplate'21 which is securedjtc'th'eplanteryframe; "A horizontal fpintle element'19holds the coupler 18 tothe camber or plate 21, thisjpin being mountedin the lugs or ears 20'."The bar 21 is rigidlyfastened'to. the cross bar22 secured tothe rearpart of the planter frame andi'extending.

' across the machinefrom-side to sidepand positioned in a'plane somewhatlower than the plane of themainframe bars 5,5, 7.

Thehin'ge element on the arm 14 which is oo'mpanioned to the hingepintle 17 is an ly tothe pintle.

aperturedbar formed with the part 23, the shank 23 and the shortrearward proiecting extension 24 having afguidehead or cam like part 25.This hinge element of the arm is secured theretoby inserting the shank28 into the sleeve like part 16' and securing it therem byrivets 26. i

In the part 23 of the extens on there 18 a vertical cone-shaped aperture23* through Which passes the hinge pintle This aperture tapers ornarrows upward, its diameter atv the upper end permitting it to fitsnug- As it flares: orwidens 1 downward it permit-s'the arm to vibratein vertical planes and the. pintle 1'? permits. ititoswing horizontally.And as the coupler 18-is connecteditothe bar 21 by. a horizon tal pivot19the arm can move bodily around the axisof the pintle 19. e

The bar or plate 21 extendsr'earward and at. its outer end is. formedwith a lip or flange 27 havingan inclined cam-like edge 17 to swingoutward and liability for the breakage of the arm or connecting parts 18I obviated. Butsu-itable stops are provided. I the pintle 27 This is atradialjd-istance fronrtlle pintle 17 equal to the distance of'the guidevheador cam 25"on the inner end-of the arm' from said pintle.Consequently, when the outer end of the arm swings: horizontally forwardthe rearward projecting extension 24 impinges on the camedge at 27 andsaid extension serves asa short arm lever to lift the outer end ofthearm up from the ground." The coupler 1 8 permits the pintle whichprevent the coupler .18 and 17 from rocking inward.

The clamp collar 33; at the outerend of. i the sleeve part l6 of-themarker arm is formed'with an eye .orhook28 to which is 7 attached a rope29 thatextends forward to and through a guide on; the neighboringcheojkhead, and thence across the machine and to and through a similarguide on the other check head, and thence to the forward end of theopposite marker arml4 to which 1 though some of them are sitely 1nCllIGCtlOIL theendof the rope i'sattached. The two arms, 14 and 14', aresimilar to 7 each other and the smp'porting and guiding. devices at thelnner end of one are similar tothose at the inner end of the other,alpositioned oppo- The length of the rope 29- is such that when thearm14 is extending outward and downward, and is in working position theouter end of the opposite arm 14 will, be

' directed forward from its hinge and willbe elevated abo vethe ground;and the latter will beheld up in its extremeposition'while thearm' 14 isin operation. i 2

At the outer end of the adjustablerod element of each arm: is theblade30. It

it may formed separately and rigidly fastened to the rod. This blade hasa downward extending shank part 31 which widens transversely, and as itwidens, is turned or twisted as shown so as to bring the forwardapproximately vertical face around toward hinge 19, the entireconnecting. or coupling device 18 SWHIgIDg' w th it during suchforwardand backward movement.

Its. outer end is automatically raised or lifted to an elevated planewhen it is being drawn forward by the rope 29'. This lifting is causedby the short lever arm 24 when its guide. head or cam. impinges on the,

underside of the guide flange orlip 27. When the 'marker'arm 14approaches the position on the righthand side of the machinecorresponding to that occupied by the arm 14', as shown in Fig.1, theextension or short lever arm 24 swings the cam or head 25 backward andbrings it, to a position where it contacts with the lip or-flange' 27,and the latter being-fixed, the parts25 and 24 areforced downward. Andthey ing part of the arm andcause itsouter end to rise until" it reachesits forward and uppermost position.
